"Before you know it, administrative work takes longer than your main business"——creating estimates, sending contracts, delivering work, issuing invoices, confirming payments. If you're doing it alone, just this takes up your entire day. Do you have this kind of concern?
Crewbook is a tool that connects this entire workflow into a single screen.
With formats that account for invoices (qualified invoices), electronic bookkeeping laws, and the new freelance law, this entire workflow is completed within Crewbook alone, without needing external service integrations. (Accounting also supports freee integration)
Since line items are inherited from previous documents, creating an invoice feels more like "confirming" than "creating." The task of recreating invoices one by one at month-end is virtually eliminated.
When projects increase and you can't keep up, you can find collaborators through Crew (Pro feature). Because you have a foundation from sales through invoicing, the workflow doesn't break down even when you delegate to others.
First try Free with up to 3 projects, and if you feel it's working, move to Pro's free trial.

「気づいたら、本業より事務作業のほうが長い」——見積を作り、契約書を送り、納品して、請求書を起こし、入金を確認する。一人でやると、これだけで一日が溶けます。こんな悩み、ありませんか。
Crewbook は、この一連の流れをひとつの画面につなげるツールです。
インボイス（適格請求書）・電子帳簿保存法・フリーランス新法に配慮した書式で、外部サービスの連携なしでも、この流れが Crewbook だけで完結します。（会計は freee 連携にも対応しています）
前工程の書類から明細を引き継ぐので、請求書は「作る」より「確認する」に近い感覚です。月末に請求書を1枚ずつ作り直す作業が、ほぼなくなります。
案件が増えて手が回らなくなったら、Crew（Pro 機能）で協力者を探せます。営業から請求までの土台があるから、人に任せてもフローが崩れません。
まずは Free で3案件まで試し、手応えを感じたら Pro の無料トライアルへ。
